A Preparation and application diagram of traditional PDA nanoparticles and PDA nanofibers. B Optical photograph of PDA nanofibers aerogel (C) SEM image of PDA nanofibers. D HRTEM image of PDA nanofibers. The red line shows the π–π stacking spacing. E XPS survey spectra and element proportion of PDA nanofibers. F UPLC-MS spectra of PDA nanofibers solution. G Graphical result of molecular stacking at time t (t = 0, 20, 50, and 100 ns) in GROMACS and specific characteristic structures and corresponding interlayer spacing. H XRD patterns of PDA nanofibers. I Raman spectra of PDA nanofibers.
